I have been wondering how hard it is to build a pivot steer garden tractor, I would probably use 2 donor garden tractors, for the axles, gearbox and engine. i was wondering about using 1 inch box section for the chassis, i would like to build it so that it is 4 wheel drive. I have drawn what i was thinking of designing, i am not particulaly good with google sketch up, i would use an engine with a horizontal drive, 10- 20hp probably. i would have an idler on the belt connecting the front and back axles. i would like to set up a pair of belts to go from the engine to the first axle, both with an idler that can be used as a clutch, it would have one belt for forwards and one for backwards, it is likely to be controled by a second clutch peddle, one forward, one backwards. has anyone got any surgestions, especialy for the pivot.
I have limited tools, parts and time, i have only acess to tools we have on the farm, drill, welder, grinder and some hand tools. I'm nearly 15, so the design needs to be fairly simple, but i will get dad to help with some of it. we have a fair selection of old parts, at the farm, i will probably get 2 garden tractors to start from, two westwood?
Thanks for the ideas, and replies, it gives me some confidence in the idea
